I am making a flutter application where I have my backend as C++. Through dart ffi I am signalling a load call when user enters a certain screen. My problem is Im loading audio in C++ but I want to signal dart that the loading has finished so that I can stop showing a loading screen. AFAIK, there is no way to call dart from C++. I have seen that you can use FromFunction. Source here.
How can I call a void class method with no parameters? or How can I call dart code from C++?
Ps: I think this is impossible to do this as of now (without work arounds). Dart devs please add this feature as it is very useful to be able to make calls to dart to process information 🙏
